Dataset: Hummingbirds use wing inertial effects to improve maneuverability.

This dataset contains the wing kinematics and mass distribution of the two hummingbirds used in the study. The wing kinematics were reconstructed from digitized high-speed videos of flight experiment in Cheng et al (Journal of Experimental Biology 219 (22) (2016) 3518–3531.).  Wing mass distribution was scaled from experiment data of Ruby-throated hummingbirds.


## Description of the data and file structure

The dataset is organized as follows:

1) Under ./bird1/digitized_marker_data/

- .xls file that contains x,y,z coordinates of body and wings marker points (total 21 points) digitized from three high speed videos.
- domainTranslation_xyz_bird1.xls file that contains x,y,z shift of the domain.
- .pdf file to illustrate the position of marker points on the bird's body and wings. 

2) Under ./bird1/mesh3dFiles/

- Sequence of marker files at all time steps for bird 1; each contains the unstructured mesh of the wings/body, including connectivity, xyz coordinates and uvw velocities of each node. 

3) Under ./bird2/digitized_marker_data/

- .xls file that contains x,y,z coordinates of body and wings marker points (total 21 points) digitized from three high speed videos.
- domainTranslation_xyz_bird2.xls file that contains x,y,z shift of the domain.
- .pdf file to illustrate the position of marker points on the bird's body and wings. 

4) Under ./bird2/mesh3dFiles/

- Sequence of marker files at all time steps for bird 2; each contains the unstructured mesh of the wings/body, including connectivity, xyz coordinates and uvw velocities of each node.

4) Under ./wingMass_data/

- .xls file that contains wing mass distribution of the Ruby-throated as well as scaled Rivoli's hummingbird wings.
